摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent element having high durability.

SOLUTION: There is provided a compound represented by the general formula. (In the formula, Z1-Z4are each independently a carbon atom or nitrogen atom; A1is an atom group forming a 5 or 6-membered heterocyclic ring with Z1and a nitrogen atom; B1is an atom group forming a 5 or 6-membered ring with Z2and a carbon atom; C1is an atom group forming a 5 or 6-membered heterocyclic ring with Z3and a nitrogen atom; D1is an atom group forming a 5 or 6-membered ring with Z4and a carbon atom; n is 1 or 2; L is a single bond or a linking group; and G is a fused ring with at least three rings, provided that the rings formed by A1to C1do not contain a fused ring with at least three rings.).
